Default 2.3 Idle When Compressor kicks on

Curious as to thoughts on where to start to fix my last issue on the new ranger. When my truck is at idle and A/C is on, the compressor kicks on and off several times a minute. Also, the RPM's get really low (not sure how low due to no tach, YET) but very low. The A/C blows cold constantly but the compressor just seems to cycle on and off way to often.
Again any help is greatly appreciated.

Also, I thought about raising to the idle due to how low the RPS are getting when the compressor comes on. (the truck shutters when compressor cycles) I found out that this is all electronically controlled and not adjustable.

Clean you IAC and check the freon charge level. If it is low your compressor will do that. I had that problem last year. I'll bet your freon (134a) is low causing your compressor to strain and it is compounded by a dirty IAC. Even with low freon your A/C will be cold if your compressor is good. The low freon will damage your compressor though.
